Messer expands further in Sichuan, becoming gas partner for BOE Chengdu's G8.6 AMOLED line

In May 2025, Messer — the world's largest privately owned specialist for industrial, medical and specialty gases — partnered with Chengdu High-Tech Investment Group to hold a start ceremony for the bulk gas supply project of BOE's G8.6 AMOLED production line in Chengdu, Sichuan, China. The event marked the official start of Messer’s supply system, providing essential infrastructure to support the next phase of BOE’s high-end display manufacturing.

As the official gas supplier to BOE’s Chengdu site, Messer will invest approximately RMB 250 million in the first phase to build an advanced bulk gas system tailored to BOE’s production needs. This system will deliver ultra-high purity nitrogen, high-purity oxygen, hydrogen, and carbon dioxide — all critical gases required in AMOLED manufacturing. A second-phase expansion is planned as a long-term strategy.

“As a leading player in the global semiconductor display industry, BOE’s track record of innovation and sustainable growth have set a strong example for the entire sector.,” said Bernd Eulitz, CEO of Messer Group，“We’re honored to collaborate with BOE and contribute our expertise to the it’s Chengdu project.”

This project marks the second successful partnership between Messer and BOE, following their earlier collaboration on BOE’s G6 AMOLED production line, also located in Chengdu.

Yang Guobin, Chairman of Chengdu BOE Display Technology Co., Ltd., remarked: “As a global leader in industrial gases, Messer’s technical capabilities and operational excellence were instrumental in the success of our previous project, and also helped us achieve the key objectives of BOE's Chengdu G8.6 AMOLED production line."

To ensure world-class implementation, Messer and Chengdu High-Tech Investment Electronic Group established a joint venture in September 2024 — Chengdu Gaotou Messer Gas Products Co., Ltd. The JV will oversee the entire lifecycle of the gas system — from construction to operations and long-term management.

“This project represents a deeper level of strategic cooperation between Chengdu High-Tech Investment Group and a top-tier international partner,” said a spokesperson from Chengdu High-Tech Investment Group. “By leveraging Messer’s global expertise in industrial gases, we aim to accelerate the development of Chengdu’s next-generation electronics industry.”
